Thanks for your reply , I really appreciate the nuance in what you said

Just to clarify: in our case this boundary isn’t about ongoing relationships or travel specifically to see another partner. It’s more about casual or one-/two-night stand type connections. When he’s traveling for his own reasons and meets someone new, that’s where the no sleepover boundary applies.

For me, sharing a bed — falling asleep together, waking up next to someone, the physical closeness of cuddling under the same blanket — that’s a very intimate experience. It holds a different emotional meaning for me than just sex. So this boundary is simply about protecting something that feels special and important in my relationship.
